May I suggest you at least take a look at
https://pcbros.tech/
Although it sounds like a scammy url, its part of the ToastyBros youtube channel. They seem upfront about stuff, and all the PCs on the page that are displayed for me in the UK (Although you may see different) are all under 1000 ?
If I were looking for a second system, or something half decent for the grandkids, I would be shopping there myself...
